How Cold is Space?

Have you ever wondered how cold space is? Space is a vacuum, which means there is no air or matter to transfer heat. The temperature of space is determined by radiation, not conduction or convection. The average temperature of space is -270 degrees Celsius (-454 degrees Fahrenheit), slightly above absolute zero. However, near stars, temperatures can reach over 10,000 degrees Celsius (18,000 degrees Fahrenheit). The temperature of space affects objects in space, such as spacecraft and astronauts. Insulation is necessary to protect against the extreme coldness of space, while objects exposed to the sun's heat need to be designed to withstand the extreme temperatures.
